To all whom t may. concern: Y

\ Be it known that I, CHARLES GRANT HAR- RIs, of Niles, in the county ofTrumbull and State of Ohio, have invented certain new and I usefulImprovements in Deliverers for Printing-Presses; and l do hereby declarethe following` to be'a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The object of this invention is to automat--V ically regulate thedischarge of stock, such as bags, from a printing-press ontoareceiving-table in suchmanner that it will be gradually piled onsuchtable without rubbing or smearing and from which'it may be readily Theinvention will be hereinafter fully set forth, and particularly pointedout in the claims. v

1n the accompanying drawings, Figure 1 is a plan-view. Fig. 2 is a sideelevation. Fig. 3 is a similar view showing the retardingwheels raisedin dotted lines. Fig. 4L is a diagrammatic view.

Referring to the drawings, 1 designatesa' eonveyer composed of a seriesof endless bands or tapes onto which bags are discharged vas they leavethe press impression-cylinder,

a portion only of which is outlined at 2. These tapes are caused totravel in the direction of arrow 'w by any suitable connection with thepress-gearing. At their louter or rear ends these tapes overlap a secondconveyer, likewise composed of a series of tapes 3, extended rearwardlysome distance from the rst series, and preferably on an incline towardthe rear. These tapes 3 engage rollers-4 and 5, the former mounted inbrackets secured to a crossrod 6, While rollers 5 are fast on a shaft 7,to which power is intermittently applied to effect the gradual advanceof the. tapes.

` lby ak swinging arm 9 and engaging aratchet This is- .preferablyaccomplished by a pawl 8, carried is secured to a rock-arm 13, which isactuated by a rotary cam 14'. The rotation of the latter imparts,through the means described, agradual rearward travel to the upperiiight of the series of tapes 3.

111 14 designate two retarding-stops in the form of wheels or rollers onashaft 15, which at its Iends is loosely fitted in vertically-slottedbearings 16, wherein it is free to rise and lower. These bearings areadjustably mounted on rods 17, secu red to brackets 18 on'crossrod 6, sothat the distance of the wheels from the delivery end of theinitially-acting tapes 1 may be increased or lessened, according to thestock being printed. These retardingwheels are directly above two of thetapes, and they rotate under the frictional contact therewith or withthe interposed stock. The location ofthese wheels relatively to thedischarge end of tapes 1 is controlled by the width' of the articlesbeing printed. For instance, in printing bags the wheels are so locatedthat the first one discharged from tapes 1 will at its forwardlongitudinal edge register against the lower edges of theretarding-wheels, whereupon the tapes 3 will be slightly advanced-sayabout one-half inchthe wheels 14 revolving to that extent, so that theforward edge of the next succeeding bag upon engaging the wheels will beprevented from overtaking the forward edge of the first bag. InV rthisway the bags are shingledou't on' the tapes in approximate fan fashion,the wheelslll and their shaft gradually rising under the increasedthickness of the bags thereunder. The wheels insure sufficient frictionbetween the tapes and the lowermost bag and betweenthe vseveralsucceeding superposed bags toL maintain their relative positions intravel. The depth of the slots in the opposite bearings permits theretarding-wheels to accommodate themselves words, when the eXtent of theprojection of ing the passage of each sheet and of the pile all the bagsequals the width of one.

As the bags pass from the tapes 3 they go onto a lay-boy 20, having avertically-disposed adjustable stop-gage 21. This lay-boy may beinclined, as shown in dotted lines, Fig. 4. As the forward edges of thebags contact one at a time with the stop-gage the bags are automaticallypiled with even edges one above the other. From the lay-boy, as well asfrom the outer ends of the tapes 3, the bags may be readily gathered upand removed by an attendant, care being taken, however, not to take upany bag any portion whereof is still beneath the retarding-wheels.

It will be noted that although the retardingwheels engage each bag as itis delivered from the press they cannot directly contact with the printon the face thereof, save in the case of the last bag fed from thepress. This is due to the fact that before any one bag is moved forwardsufficient to bring its print beneath the wheels the next succeeding bagis brought into position. Hence not only are the bags discharged ontothe table without danger of smearing, but the means whereby they areretained in proper relation until arrested by the stop-gage will notcome into Contact with the fresh ink of the print. As a bag contactswith the retarding-wheels the tapes are fed forward a short distance,which represents the extent to which such bag will protrude beyond theone next following. As the bags reach the stop-gage of the lay-boy theylose the shingling, and may then be removed in stacks with but little,if any, danger of smearing.

Although this invention has been found specially applicablein theprinting of bags, owing to their size and the multieoloring of theirprint, yet it is obvious that it may be employed in the delivery ofvarious kinds of stock.

I claim as my invention 1. A printing-press deliverer comprising aconveyer whereon the stock is designed to pile as it is discharged fromthe press, means for uniformly engaging each sheet as it falls on theconveyer for retarding the passage thereof and of the pile as a whole,and means for actuating the conveyer. l

2. A printing-press deliverer comprising a conveyer whereon the stock isdesigned to pile as it is discharged from the press, means within thelength of the conveyer for retarding the passage of each sheet and ofthe pile as a whole, and means for actuating the conveyer.

3. A printing-press deliverer comprising a conveyer whereon the stock isdesigned to pile as it is discharged from the press, means within thelength of the conveyer for retardas a whole, and means for actuating theconveyer as each additional sheet is added tothe pile.

4. A printing-press deliverer comprising a conveyer whereon the stock isdesigned to pile as it is discharged from the press, verticallymovablerotary wheels located above said conveyer intermediate the ends thereofand with which each sheet is designed to contact as it is dischargedfrom the press, said wheels rising as the number of sheets thereunderincreases, and means for intermittently advancing the conveyer andmaintaining the relative arrangement of the sheets.

5. A printing-press deliverer comprising a conveyer vertically -movablcwheels above said conveyer for temporarily retarding the passage ofstoel; thereon, a shaft for said wheels, vertically-slotted bearings forsaid shaft, and means for intermittently advancing said conveyer.

6. A printing-press deliverer comprising` a con veyer whereon the stockis designed to pile as it is discharged from the press, means locatedabove the conveyer within the length thereof for temporarily retardingeach sheet of stock as it contacts therewith, such means being free torise as the extent of the pile thereunder increases, each sheet and thepile as a whole being uniformly maintained, and a lay-boy beyond thedischarge end of the conveyer having a vertically-disposed stop-gagewith which the sheets successively engage.

7. ln a printing-press deliverer, in combination, an initially-actingdelivery-conveyer, a second conveyer onto which the former conveyerdischarges and whereon the stock is designed to pile, rotary wheelsabove said seeond conveyer with which each sheet of stock engages as itis deposited on the pile thereof, means for permitting said wheels torise and lower so as to conform to the thickness of the pile, means forintermittently advancing said conveyer, such pile moving therewith, anda lay-boy onto which said second conveyer discharges, said lay-boyhaving a stop-gage.

8. ln a printing-press deliverer, in combination, an initially-actingdelivery-eonveyer, a second conveyer onto which the former conveyerdischarges, rotary wheels above said second conveyer and designed to beactuated thereby, a shaft for said wheels, verticallyslotted bearingsforsaid shaft, supports whereon said bearings are adjustably held, and alay-boy onto which said second conveyer discharges, said lay-boy havinga. stop-gage, as set forth.
